Vanillin, which constitutes the active principle of the vanilla pods has been used for a long time in the manufacture of ali mentary products, and particularly in the manufacture of biscuits and of chocolate.

In the household, however, its use is almost unknown. V anillin, .as. a matter of fact, is very little soluble, and its fiavour-' 111g properties are so marked that it is difiicult to find the suitable dose wlthout special knowledge. As an excess of vanillin destroys the flavour and imparts a bitter taste, disappointment and even prejudice against the vanillin itself has been the result, and no use has been made ofv it. It has been attempted to incorporate the vanillin with sugar, but the vanillin-sugar so obtained is difiicult to use, for ho kitchen is equipped to weigh the small quantities needed in practice.

solve. Flours, for instance, contain invariably gluten and other nitrogenous matters. owing to which a paste of flour and water exhibits cohesive properties which prevent the bursting of tablets manufactured with" flour.

According to the present invention, all

the difliculties are'eliminated by supplying vanillin in the form of compressed taiblets, each of which contains an exact quantity of vanillin,mixed with a. substance adapted to swell in water such as pure starch and cellulose, said substance being Without noxious action on the vanillin or on the human body, suchas starch.

Tablets made in this manner will immedi a-tely burst in water and the liberated vanillin, in a fine'state of division will dissolve at once.

What I claim and Letters Patent is p y 1. A process of preparing doses of vanillin for culinary purposes, which consists in mixing a definite quantity of vanillin desire to secure by with a substance adapted to swell in water.

said substance being Without noxious action on the vanillin or on the human body, and compressing the mixture into tablets.

2. A process of preparing doses of vanillin for culinary purposes, which consists in'mixing a definite quantity of vanillin with starch, and compressing'the mixture into tablets.

In testimony whereof I have signed my f name to this specification.
